This plant is native from Southern Saudi Arabia Peninsula.
Caralluma flava is a perennial plant which forms succulent tiny bushes composed of many tetra-lobated green stems. It hasn’t got leaves, so the photosynthesis is done by the stems. Stems have an irregular surface. They are quadrangular with wavy edges. The inflorescence is an umbrella of bright yellow, star-shaped flowers with five petals.
Caralluma flava needs a bright spot but it should be protected from direct sunlight during the central, hottest hours. The substrate should be very well-draining and rich in nutrients. Clay pots are better because they help the process of draining of the soil. Watering should be almost avoided in winter -once a month is sufficient-, and relative to the state of the substrate in summer. Wait 1-2 days after the soil completely dries up before providing the plant with plenty of water. Repotting is necessary in the beginning of spring.
Propagation is easy either by cuttings or by seed. If you try propagation by cuttings, pay attention: the wound should be dried up before putting it into the soil.
Its name comes from Arabic and literally means “wound of the flesh”, probably referring to the unpleasant smell that the flowers of this genus give off, just like Stapelia, which is very similar.
